Oxide materials are omnipresent in science and technology. Given their low carrier density and poor screening ability, oxide properties are often inhomogeneous in space and governed by stoichiometry modulations, defects and impurities. [more]

Ultracold molecular platforms are rapidly emerging as highly tunable environments for quantum simulation. In this talk, I will demonstrate how the intrinsic stereochemistry of chiral molecules can be harnessed to engineer complex topological and many-body quantum phases from the ground up. [more]

Chemical processes at metal oxide - water interfaces are of central importance in geochemistry, biology, and energy technologies. A better understanding of these processes is essential for progress in these fields. [more]

Several non-equilibrium states in 1T-TaS2 have been discovered over the past 15 years, all of which differ significantly from its commensurate charge density wave (CDW) ground state at low-temperature equilibrium. These include the long-lived hidden domain state, which has attracted particular attention for its potential applications, an electronic amorphous state, and a range of more exotic CDW states within a single layer. All these states can be achieved with either an ultrafast optical or a short electrical excitation, providing an accessible platform for studying electronic processes in CDW materials. Understanding them is essential for uncovering the microscopic mechanisms governing metastability and dynamics, with insights that can potentially be transferred to other related systems. [more]

Electrostatic potential fluctuations in liquid water control the thermodynamics and kinetics, such the solvation free energies, the capacitance of electrified interfaces, and the decoherence of molecular qubits in aqueous environments. Most simulation work has focused on mean fields. Only recently has it become clear that the fluctuations themselves carry physics that is missed by the average. [more]
